Well the movie does introduce 2 things that are seen in the series so it really isn't filler. But it is your choice.

I actually just watched it earlier today and I'd say it's worth watching. Usually Super Sentai summer movies are very forgetable, but this one was pretty good. Also Sanjo being Sanjo, he's actually worked the events of the movie into the series like he did with Begins Night and AtoZ.

Oh shit really? What episode does that fit into?

It's also a Sentai movie, so it's 30 minutes. Not exactly a time sink :lol

You should be getting close to one of the episodes it ties into in a bit, but the big one is 39.

I only recall it ever tying into episode 39, and even then the events are summarized pretty succinctly.

I think the movie is decent but forgettable. And the only reason I can see for them reusing the characters in the series is budgetary. There's a definite budget problem from about episode 35 to episode 44, where monster suits get reused, mooks are repurposed as main monsters (in one case, by literally putting a wig and lipstick on top of a mook suit), the movie characters' are pretty inelegantly jammed into the show, and 2 new generals are introduced wearing dime-store Halloween costumes.

Maybe I'll stick to my original idea and skip it then...haha.

It lightly ties into the episode when they revive Torin by using Meeko's song.

I mean, it's totally fun spectacle and it's enjoyable in that distinctly Koichi Sakamoto way, but it's hardly relevant to the plot.

Oh yeah... But it's only because they're using a plot device introduced in the movie, right? I totally watched that episode before the movie and didn't miss a beat. I think I even recall them flashing back to the movie in-episode to explain it -- though, I could be dreaming that. :lol

It is worth watching just for the fight in the forest at the beginning of the show.
